CARL GALITZ, OF SASSNITZ, GERMANY.

CHIMNEY ATTACHMENT.

Application filed November 6, 1908.

To all whom it may concern:

Be it known that I, CARL GALITZ, a subject of the Emperor of Germany, residing at Sassnitz a. Rugen, in the Empire of Germany, have invented new and useful Improvements in Chimney Attachments, of which the following is a specification.

The invention relates to a chimney-attachment with a horizontally arranged vanewheel.

In the chimney-attachments of this kind heretofore suggested, by reason of the arrangement of the vane-Wheel, it has been inconvenient to look after the vane-Wheel and to clean the attachment. This disadvantage is obviated according to the present invention by mounting the vane-wheel on a door on the attachment. If the vane-wheel is to be inspected or the attachment cleaned, the door is simply opened and the wheel swung out.

Heretofore the spindle of the vane-wheel has been allowed to run in two step or pivotbearings, yet in this arrangement there was the disadvantage that the ascending soot was driven into the open upper bearing and the rotation of the pivot-journal on the spin dle in this bearing was impeded.

According to the present invention, this disadvantage is obviated in that, in the place of the upper step-bearing, a guide-pin orpivot is provided, which enters into a recess in the upper end of the spindle and in this manner guides the spindle.

The accompanying drawing shows one constructional form of the new chimney-attachment, viz:

Figure 1 shows the same in Vertical section, Fig. 2 in plan with the door closed, Fig. 3 in plan with the door opened. Fig. 4 shows the spindle-bearings drawn to an enlarged scale.

ney-attachment and b the door thereof; 0 is a bracket secured to this door, in which bracket the horizontal vane-wheel d is mounted. e is the spindle of the vane- Wheel, which runs at the bottom in a stepbearing 9 and at the top on a pivot f which enters into a recess in the spindle. In this arrangement, the door I) with the vanewheel d can be swung outwards (Fig. 3), for the purpose of inspecting the vane-wheel d and cleaning the casing or pipe at. The soot driven upward by the air-current or draft moves past the ste -bearing 9 and the pivotbearing f and is t us efieotually prevented from penetrating into the bearings. The rotation of the spindle is consequently not impeded.

What I claim is 1. A chimney-attachment comprising a.

tubular casing having an aperture therein, a door mounted on said casing and adapted to close said aperture, and a vane-wheel rotatably mounted on said door.

2. A chimney-attachment comprising a pipe having an aperture therein, a door ivotally mounted on said pipe and adapter to close said aperture, a bracket on said door, a spindle rotatably mounted in said bracket, and a vane-wheel mounted on said spindle.

3. A chimney-attachment comprising a tubular casing having an aperture therein, 'a door mounted on said casin and adapted to close said aperture, a spindle, a vane-Wheel mounted on said s indle, a pivot-pin mounted on said door an extending into a recess in the upper end of said spindle, and a stepbearing mounted on said door and receiving the lower end of said spindle.
